Which current medication should be reviewed when treating a Clostridioides difficile infection with vancomycin?

• A. Lansoprazole
• B. Ramipril
• C. Amlodipine
• D. Atorvastatin

Answer: (A)

Proton pump inhibitors like lansoprazole are important to review in this context because suppression of stomach acid is a known risk factor for acquiring and recurring Clostridioides difficile infections. Keeping a PPI on board during treatment with vancomycin may influence the disease course, so if there’s no compelling reason for acid suppression, reducing or stopping the PPI can help minimize recurrence risk and support recovery. Vancomycin for C. difficile acts mainly in the gut and has limited systemic interactions, so the focus is on modifying this risk factor rather than drug interactions with the antibiotic. The other medications listed (an ACE inhibitor, a calcium channel blocker, and a statin) do not have the same documented impact on C. difficile infection risk or on vancomycin’s effectiveness in this scenario.
